The invention relates to an improved blended fabric processing method and aims to solve the technical problems that a conventional processing method is too complex in step, takes a great deal of time,is low in processing speed, and the like. The improved blended fabric processing method comprises the following steps: a, taking a blended fabric of a sea-island fiber and a polyamide fabric; b, weighing 25 parts of polyvinyl chloride, 18 parts of an epoxy resin, 2 parts of titanium dioxide, 4 parts of nano copper oxide, 1.2 parts of an anti-mold agent, 2 parts of a cross-linking agent, 0.2 partof a defoaming agent and 30 parts of a solvent; c, stirring the polyvinyl chloride, the epoxy resin, the titanium dioxide, the nano copper oxide, the anti-mold agent, the cross-linking agent, the defoaming agent and the solvent in a preparation device so as to obtain a coating liquid; d, uniformly coating the surface of the blended fabric with the coating liquid; and e, drying the coated blended fabric in a drying oven, thereby obtaining a finished product. The method has the advantage of being high in processing speed.
